Transition metal complexes of 1,10-phenanthroline

Transition metal complexes of 1,10-phenanthroline ("phen") are coordination complexes containing one or more 1,10-phenanthroline ligands. Complexes have been described for many transition metals. In almost all complexes, phen serves as a bidentate ligand, binding metal centers with the two nitrogen atoms. Examples include PtCl2(phen) and [Fe(phen)3]2+.
